Method of displaying a graphic containing contours on a display unit |
摘要 |
Displaying a graphics such as for example a diagram or a map on a display unit of a portable device requires a reduction in the number of pixels. In each case this requires a decomposition of the graphic into a number of blocks. To do this each block is usually subjected to what is known as "subsampling°. In such cases the semantically important contours disappear at least partly so that the content of the graphic is lost. To resolve this problem to a method is proposed which for a specific application assigns a weighting to the colors underlying the contours. For the reduction in dominant color is determined depending on the result of the weighting and this is simulated in a further procedural step from a set of specified basic and pseudo colors. In this way the semantically important contours of a graphic and thereby the readability are retained despite the fact that reduction has been undertaken.
